NEET Physics Speed & Velocity MCQ Question
Type: MCQ-diagram based-Hard-Class 11
Consider a velocity-time graph that shows motion with constant acceleration, where the object changes direction at a certain point. Which of the following correctly describes the behavior of velocity at the point of direction change?
A
Velocity becomes zero before reversing direction.
B
Velocity remains constant and non-zero while changing direction.
C
Velocity increases as the direction changes.
D
Velocity decreases continuously without becoming zero.
Correct Answer
Option A
Detailed Explanation
In the NCERT context, when an object changes direction, its velocity must momentarily become zero before reversing, as indicated by the velocity-time graph for motion with negative acceleration.
